摘要:
Provided are a chemical mechanical polishing (CMP) composition used for polishing a semiconductor device which contains polysilicon film and insulator, and a chemical mechanical polishing method thereof. The CMP composition is especially useful in a isolation CMP process for semiconductor devices. Provided is a highly selective CMP composition containing a polysilicon polish finisher which can selectively polish semiconductor insulators since it uses a polysilicon film as a polish finishing film.
